Hi,
I'm quite new to lustre, studying all the documentation. A question I
have not found an answer to so far:
If the user data gets spread out in chunks to a number of OSTs, and one
of the OSTs fails completely - say, all the disks on the fileserver
behind that OST are gone for good - how does the cluster recover from that?
It can't be a backup replay from tape or keeping all fileservers as HA
pairs, right? Is lustre doing some kind of RAID accross the OSTs? And
where can I find some documentation on that?
Thanks,
Thomas
